 * An implementation of {@link HttpPartParser} that takes in the strings and tries to convert them to POJOs using constructors and static create methods.

 * 
 * <ul>
 * 	<li>
 * 		An <jk>enum</jk>.
 * 	<li>
 * 		Have a public constructor with a single <code>String</code> parameter.
 * 	<li>
 * 		Have one of the following public static methods that takes in a single <code>String</code> parameter: 
 * 		<ul>
 * 			<li><code>fromString</code>
 * 			<li><code>fromValue</code>
 * 			<li><code>valueOf</code>
 * 			<li><code>parse</code>
 * 			<li><code>parseString</code>
